Wheaton 300mL BOD Bottles with Pennyhead Stopper & Barcode Label

Wheaton Science 300mL B.O.D. Bottles with Glass Pennyhead Stopper and Bar Code Labels are available in both un-numbered as well as numbered sets. Numbered B.O.D. bottle sets are provided in 24-count sets beginning with "1 to 24" and ending with "409 to 432". These 300mL B.O.D. bottles are recommended for the five-day B.O.D test. B.O.D. bottles are used for incubating diluted samples of sewage, sewage effluents, polluted waters, and industrial wastes to determine the amount of oxygen required during stabilization of the decomposable organic matter by aerobic biochemical action. Interchangeable ground stoppers are tapered to prevent air entrapment. Bottles have a flared lip for water seal. A second white label on these B.O.D. bottles also make it easy to identify samples.
